As shown in fig. 2, the method comprises the steps of:
s201: sending a random number to the first data providing end, so that the first data providing end generates a first data calculation result according to the random number and first to-be-compared data of the first data providing end, and sending the first data calculation result to the second data providing end.
The first data calculation result is used for indicating the second data providing end to generate a second data calculation result according to the second to-be-compared data of the second data providing end and the first data calculation result, and the second data calculation result is sent to the data comparison opposite end.
Optionally, the random number and the first to-be-compared data of the first data providing end generate a first data calculation result, and a sum of the random number and the first to-be-compared data of the first data providing end is the first data calculation result.
Optionally, the second data to be compared at the second data providing end and the first data calculation result generate a second data calculation result as follows: and the difference between the first data calculation result and the second data to be compared at the second data providing end is a second data calculation result.
Alternatively, the random number may be generated by a hash algorithm.
In a possible implementation manner, the data comparison end distributes own data demand information (bidding documents, goods purchasing demands and the like) to the block chain network in a broadcast message manner signed by own private key, and simultaneously sends a random number R to the first data providing end independently (note that the random number R is only sent to the first data providing end, but can not be known by anyone to know the specific numerical value, so that the random number can be encrypted by using the public key of the first data providing end to obtain an encryption result, and then the encryption result is sent to the first data providing end).
And after receiving the encryption result, the first data provider decrypts the encryption result by using the private key of the first data provider to obtain the random number R, and then the first data provider makes a price quotation according to the requirement of the first data provider. And the first data providing end carries out quotation according to the requirement of the first data providing end. Assuming that a first data provider offers a price a (first to-be-compared data), the first data provider calculates a + R to obtain a first data calculation result, and then the first data provider sends the first data calculation result after signing by a private key to a second data provider.
After receiving the information, the second data providing terminal verifies the private key signature of the first data providing terminal, if the verification is passed, the second data providing terminal offers price b (second data to be compared) according to the bidding requirement of the second data providing terminal, the second data providing terminal subtracts b from the received first data calculation result of the result a + R to obtain a + R-b, namely a second data calculation result, and then the second data providing terminal sends the second data calculation result to the data comparison opposite terminal after the private key signature.

Optionally, after determining the comparison result between the first data to be compared and the second data to be compared according to the second data calculation result and the random number, the method further includes: sending a first data to be compared to a first data providing end to obtain a request; sending a second data acquisition request to be compared to a second data providing terminal; receiving first data to be compared sent by a first data providing end and second data to be compared sent by a second data providing end; and comparing the validity of the result according to the first data to be compared, the second data to be compared and the random number.
In a possible implementation manner, after the whole comparison process is finished and the data comparison end publishes the bid result in the form of a broadcast message signed by a private key of the data comparison end, the data comparison end requests the first data providing end and the second data providing end to obtain the values of the quotation a and the quotation b. And (4) calculating the value of a + R-b by the data comparison opposite terminal, and if the value is consistent with that sent by the second data providing terminal, the data passes the verification, and the data comparison is proved to be effective. The whole comparison process is simply added or subtracted without complex encryption and decryption calculation on the premise of achieving the target. Therefore, the data comparison greatly improves the efficiency and saves the calculation time and resources.
After the data comparison opposite end realizes data comparison, the data comparison opposite end can send data acquisition requests to be compared to the first data providing end and the second data providing end, validity authentication is carried out on the comparison process through the acquired data, whether an error phenomenon occurs or not is determined, data safety is further guaranteed, and user experience and fairness of data comparison are improved.
